Denon Technology

DENON Link: Connected via a shielded twisted pair (STP) RJ-45 fitted cable

to a DENON Link-compliant A/V amplifier, the balanced signal transfer offers

lower voltage than coaxial or unbalanced cables. Since DENON Link is far less

susceptible to radiated noise, it ensures the highest level of signal transfer. The

DENON Link interface is able to transfer high-grade LPCM 24-bit, 192-kHz,

2-channel and 96-kHz, 24-bit, multi-channel digital output.

Advanced AL24 Processing: Denon led the world in developing a practical

PCM recorder in 1972. The shift to digital technology solved numerous prob-

lems such as noise, wow, flutter, and frequency response. The delicate nuances

of sound from CD up to the least significant bit (LSB) are lost, however, due to

the 16-bit quantisation and band cutting at fs/2 (half the sampling frequency)

during 44.1-kHz sampling. Denon was determined to tackle the problem of

quantisation noise that remained in digital audio, and developed ALPHA (adap-

tive line pattern harmonised algorithm), a technology that reproduced 16-bit data

with 20-bit quality and became a favorite with audiophiles around the world.

This development later progressed to 24-bit quality with the evolution of "AL24

Processing," and as support for higher resolutions and sampling continued to

improve, Denon developed "AL24 Processing Plus" for the 192-kHz sampling of

DVD-Audio.

Denon's most recent achievement is "Advanced AL24 Processing," a propri-

etary high-speed signal processing technology that expands the volume of data

along the time axis in addition to the data expansion of existing AL24 Processing

Plus technology.

AL24 Processing Plus: Denon has further developed its proprietary AL24

Processing, an analog waveform reproduction technology, to support the

192-kHz sampling frequency of DVD-Audio. This new technology, called AL24

Processing Plus, thoroughly suppresses quantisation noise associated with

D/A conversion of LPCM signals to reproduce the low-level signals with opti-

mum clarity that brings out all the delicate nuances of the music. In high-end

models, AL24 Processing Plus works for all channels.

LAMBDA SLC: The LAMBDA Super Linear Converter (SLC) design includes a

LSI, developed by Denon, that divides the digital data into two streams to elim-

inate zero-cross distortion in a powerful DAC configuration. In the two data

streams, there is no reversal of the MSB, and the combined waveform also

shows no zero-cross distortion. Even if there is distortion in the original informa-

tion for a certain bit, the two signals are averaged, reducing the distortion by one

half. On the other hand, if the signal level is larger than the amount of shift, the

waveform will pass through the usual, unbiased zero-cross point and any dis-

tortions in the signal will then be reliably eliminated by the MSB compensation

feature of the SLC.

DDSC-Digital, for High-quality Sound Reproduction: DDSC (Dynamic

Discrete Surround Circuit)-Digital is a circuit configuration specially designed by

Denon in which all elements of the surround processor are optimised through

the use of selected high-performance discrete components, including separate

A/D and D/A converters, with sophisticated DSP surround decoding.

All Channel Equal Circuit: Denon's A/V amplifiers and receivers are

endowed with power amplifiers that deliver equal power and response to all

channels, ensuring utter fidelity to a wide range of high-quality sound sources,

from 2-channel stereo to advanced DVD-Audio, Super Audio CD, and Multi

channel A/V sources such as Dolby Digital EX and DTS-ES. This all-channel

equal circuit gives you the same quality sound in any format and in all channels.

The power sections of Denon's A/V amplifiers and receivers use large trans-

formers, high-capacity block capacitors, and other parts specially selected for

their high-quality sonic characteristics to give you a robust yet wonderfully

detailed sound.

Pure Audio Construction: A/V components contain analog audio, digital

audio, video, control and many other circuits. The various circuits and blocks in

Denon’s A/V amplifiers and receivers are thus separated and shielded to pre-

vent mutual interference among them. High-end models are designed with the

power supply section in the centre and the power amp section on both sides

as in a Hi-Fi amplifier.

Pure Direct Mode:

Pure Direct mode allows listeners to enjoy pure music of

remarkably high quality. When Pure Direct is selected, power to the video cir-

cuitry and the fluorescent display is automatically turned off. During analog sound

input, power to the digital circuitry is also turned off, and adverse influences by

other circuits on the audio circuitry are suppressed to the maximum extent pos-

sible.

Rigid Vibration-resistant Chassis for High-precision Playback: As in

pure audio components, A/V receivers must also be thoroughly protected

against the adverse influences of both internal and external vibrations. Denon

products are built with a sophisticated vibration-resistant chassis that effectively

eliminates these adverse influences on sound quality.

Supports Next Generation High Resolution Formats: Future system

upgrade capability is provided with the Denon's A/V receivers 6/8 Channel

External Input feature. For next generation high resolution multi-channel audio

formats such as DVD-Audio and Super Audio CD, the 6/8 Channel External

Input is equipped with a wide band frequency response extending to 100 kHz.

In addition, the digital inputs support high resolution 24 bit, 96 kHz stereo PCM

soundtracks, available on selected audiophile DVD music releases.
